nxnaocAxnoN moron- To'all whom it may concern.'

Be it known that I, LIONEL MJ WoOLsoN, a `citizen of the United States, and resident of Detroit, Wayne County, State of Mich? igan, have invented certain new and useful Im rovements in Hydrocarbon Motors, of vwhich the following is a specification.

This invention relates to hydrocarbon motors and particularly to means for heat-ing l0 the mixture thereof. l A

One of the objects of the present invention is to 'provide a heater device for the air intake of a carburetor. y

Another object of the invention is to provide a combustion heater in connection with the carburetor air intake to thereby provide a heated mixture for the motor.

Another', object of the invention is to provide a mixture valve of simple c0nstruction in the gasoline feed line of the motor.

Another object of the inventiomis to automatically control the operation of va coin,- bustion heater.` v

Another object of the invention is to provide thermostatically controlled means for cutting out the action of the combustion heater when the gases in vthe intake pipe 'reach/a predetermined temperature. Other objects of the invention will appear from Ithe following description taken in connecton with the drawing which forms a part of this specification and in which the figure l isa vertical section and part elevation of motorv parts embodying my invention.

a, motor intake pipe 4or conduit to which is connected Ya carburetor 11 as by bolts and flanges 12. The upper or outlet part' of the carburetor forms a continuation of the conduit 10 and a butterfly throttle valve 13 isfarranged in the conduitfor control of the quantity of mixture passing to the motor.

The carburetor in question has a mixing tube 14: surrounding a fuel nozzle 15, which r nozzle is sup lied'with gasoline or other fuel from a oat chamber 16'in the usual way. The carburetor has two air intakes or assages, an auxiliary air intake 17, which 1s controlled by a spring closed valve 18, suppl ing air to the carburetor around the outsi e of the mixing tube 14, and a main Referring to the drawings, 10 indicates P intake 19 supplying ainto the interior of the tube 14 and around the nozzle 1li.

For ,the purpose of providing a heated mixture tothe intake pipe ,10, the main lair 20 thi-ou which are numerous openings 21 by w ich the air enters the intake 19.v

-intake 19 is provided with a'heating jacket The heating jacket 20 `is supplied with a,

suitable combustible mixture from a mixture valve- 22, which will be hereinafter more fully described, throughs. pipe 23, the mixture entering the" 'acket at 24, adjacent a spark vplug 25 which After the mixture has burned `in the jacket ignites the mixture.

2( it passes out through an outlet 26'anda Y pipe 27 to the intake pipe 10, wli'ich it enters at 28, above the throttle valve 1'3.

Thus' the suction ofthe motor abovethe` throttle valve 13 produces the depression-in the jacket 20- which draws mixture from the'valve 22 for `supplying the heating jacket.l As the heating jacket is .ke t very vwarm by the constant burning of t e.mix

1 rPhe mixture valve 22 above referredtois arranged 'in' the gasoline line.29 that sup plies the float chamber 16.1 A` three-way vlug valve 30 controls theA passage of fuel 1n thisline and ermits'gasoline tofflow both to the float c amber 16 and the valve 22 as.it is shown in the, drawing, orfthe valve may be turned 180`to cutoif="th'e valve 22 .and still supply the oab'chainber 16,' or again the valve vma vbe turned -900 to cut off both the float ,c 'amber' and the valve 22, orto cut o the '.float chamberand permit the valveV 22,'to .bevsupplied The, valve 22 'consists of a casting forming a mixing Tchamber 31 .having a'gas line inletportj32 and air *ports Alg33.` The air ports .areadjustably .controlledby a surrounding ring 34 which may be turned to open the ports 33 more or less. A

The gasoline port ,u32 may controlledv by l va needle valve 35 which extends upwardly valve-35 is provided with a iiange 39 which' may cover the ports 38 when the valve is in its closed position. An inwardly extending lange 40 is arranged in the chamber 31 adjacent the fuel port 32 to cause the upwardly moving air in the chamber to Apass close to said port 32 and therebymix with 'the gasoline issuing from said port.

T'he .valve 35 has a stem 41 which is adapted to abut against a stop 42 which is adjustably mounted in the cap 43 at the top of the casting. `A spring 44 assists in yieldingly holding the valve in its closed position, this spring having one end against the liange 39 and the other end against a shoulder 45l on the stop 42. A nut 46 locks` lthe stop 42 in adjusted position.

The outlet from the chamber 37 to the tube'23 above referred tois shown at 47. .As suction is createdA in the tube 23, the depression 'in' the chamber 37 causes the valve 35 to be drawn from its seat and thus open| slightly the port v32. Thus gasoline is drawn through said port and air is drawn through the porte 33 which mixes with the gasoline land forms a combustible mixture which passes to the heater jacket 20 through the ipe123. When the suction ceases, as

the stopping of the motor, the spring 44 prevents escape of gasoline at the port 32.

In case it is desired to use the heater merely for warming up the motorand not during its continued operation, aS thermostatic device for controlling the heater may I be employed. In the form shown a thermostatr48 may be arranged in the intake pipe t 10, preferably abovel the throttle 13 and above` the int 28 where the burnt gas enters the intake pipe. This thermostat consists of a plug 49 threaded into the intake pipe and grounded thereon or as shown at 50. One arm51 of'the thermostat is connected to this plug 4i), this arm being foi-'ined of two pieces of' metal diii'ering in (1o-elliciency-of e'xpansionso that the arm is bent away fron! the arm 52 whichis similarly 'formed and extends adjacent to it. The arm 52, however, is insulated'A from the arm 51 as by an insulating block 53 and a bolt 54- pass'es through the block 53 to the outside of'tliepliig. In the drawing the arms 51 and 52 are shown in contact as at 55 and the circuit, therefore, is closed through them. Asl the gases passing through the intake' pipe become heated the arms 51 are separated and .contact at is broken.

The outeren'd of the bolt 54 is connected through a conductor 56 witha battery 57 which in turn through a conductor 58is Lacasse winding 64 of the coil above re,- o

, by the motor or other device to create a spark in the heater jacket 2O to fire the .charge therein and this operation will continue as long as contact is maintained at 55. It is believed that the operation vof the device is'clear from the above full description..

Other forms of devices than thatk shown may be made without departing from the spirit or scope of the invention.
